A research team led by Prof. Zhang Tianshu at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has ...

That creates atmospheric instability, the other key ingredient for tornadoes. El Niño’s weakening was a warning This perfect combination of ingredients for tornadoes wasn’t a complete surprise.

While trying to determine if it could use the entire Earth's atmosphere as a massive sensor, the US military’s Defense Advanced Research Projects Agency (DARPA) made a highly unusual detection.

This additional energy fuels the storm system, leading to stronger winds and greater atmospheric instability. That leads us to the second necessary condition for a storm: atmospheric instability.

Scientists think changes in the jet stream may help explain the uptick in storms — with increasing atmospheric instability possibly affecting areas under the flow of fast-moving air — but it ...
